Abstract.Anthropogenic activities in catchments can alter the light regimes in downstream natural waters, affecting light attenuation and the perceived optical properties of the waters. We analyzed the effects of upstream hydropower operation and oligotrophication on light attenuation and reflectance in Lake Brienz (Switzerland). For this purpose, we reconstructed its light regime for the pre-dam condition and for periods of 4-fold increased primary productivity, based on direct observations of… 
Effects of alpine hydropower operations on primary production in a downstream lake
Abstract.During the past century, the construction of hydropower dams in the watershed of Lake Brienz has significantly altered the dynamics of turbidity, which has important implications for lake
Comparing effects of oligotrophication and upstream hydropower dams on plankton and productivity in perialpine lakes
In recent decades, many perialpine lakes have been affected by oligotrophication due to efficient sewage treatment and by altered water turbidity due to upstream hydropower operations. Such
Effects of oligotrophication on primary production in peri‐alpine lakes
During the second half of the 20th century untreated sewage released from housing and industry into natural waters led to a degradation of many freshwater lakes and reservoirs worldwide. In order to
Effects of impoundment on nutrient availability and productivity in lakes
We investigate the hydraulic alteration and the effect on primary productivity of the Hugh Keenleyside Dam built at the outlet of the Arrow Lakes (British Columbia, Canada) in 1967. Three dam‐induced
Present and past bio-available phosphorus budget in the ultra-oligotrophic Lake Brienz
Abstract.A detailed budget of the fluxes of bio-available phosphorus (bio-P) was established for the ultra-oligotrophic Lake Brienz (Switzerland) and its catchment. Lake Brienz is a cold, deep
Effect of sediment and nutrient loading on Lake Tahoe optical conditions and restoration opportunities using a newly developed lake clarity model
A quasi‐two‐dimensional lake clarity model (LCM) was developed to better understand the impacts of pollutant load on lake/reservoir water quality and to provide guidelines for lake/reservoir
Spatial and temporal variability in water transparency in Yunnan Plateau lakes, China
Water transparency (represented by Secchi disk depth, SDD), a key physical feature of lake ecosystems, is directly controlled by optically active substances, including organic matter (concentration
Impact of hydropeaking on hyporheic invertebrates in an Alpine stream (Trentino, Italy)
TLDR
The main trophic roles represented in the hyporheic assemblages do not support an important role for biological interactions such as predation in determining the fine-scale patchiness of the hypora, resulting in the recorded faunistic pattern.
Transformation and Simplification of Aquatic Vegetation Structure and Reoligotrophication of a Lake During the last 40 Years
The recovery or reconstruction of aquatic vegetation has recently been reported as a result of water quality improvement after anthropogenic eutrophication. The objectives of this study were: to
Bottom-up control of whitefish populations in ultra-oligotrophic Lake Brienz
TLDR
Evidence is presented that cladoceran biomass governs food consumption by the fish («bottom- up effect»), while the effect of fish predation on cladocers was found to be negligible, most likely also during the period of poor growth.
